Is nihilism the logical extreme of atheism?

[fr0d0]

Good as in functional. That's the root meaning of good.

The Natzi gas chambers were functional, but they weren't good at least not in any moral sense of the word.

If god isn't good as in, "that which is morally right" but merely as, "having the qualities required for a particular role" i.e. that of creator, then I see no difference between the proposed goodness of god and the big bang.

The singularity is perfectly 'good'. It is functional in that it brings about a universe. God, having produced said singularity, has to be superior to it (see Aquinas). So Good is morally superior to the universe, and needs to be perfectly good.
